Lateral Force Microscopy (LFM)

By CSInstruments

NanoMechanical Mode Mapping Surface Friction with Precision Lateral Force Microscopy (LFM) is a specialized Atomic Force Microscopy (AFM) mode for measuring surface friction and detecting nanomechanical variations. By analyzing lateral deflections of the AFM probe, LFM provides detailed insights into frictional forces and material heterogeneity, making it ideal for tribology, materials science, and nanotechnology applications. Key Features LFM Mode - Friction Mapping: Quantify nanoscale variations in surface friction with high sensitivity. - High Resolution: Achieve sub-nanometer spatial resolution. - Versatility: Suitable for hard and soft materials in ambient or controlled environments. - Simultaneous Data Collection: Combine with topography for correlated analysis. - Wide Applicability: Analyze polymers, composites, coatings, and biological samples. Applications of Lateral Force Microscopy Tribology Studies - Investigate surface lubrication and wear properties. - Analyze frictional behavior of functional coatings and films. Materials Science - Map heterogeneity in composite materials and polymers. - Study phase separation and nanoscale frictional variations. Biological Samples - Examine frictional forces in biomaterials and tissues. - Characterize the surface properties of biological samples. Two AFM images of the same graphene spot compare surface morphology (topography – left) and material interactions (friction mode – right), highlighting nanoscale structural and frictional variations. How does LFM Mode work? Lateral Force Microscopy measures frictional forces by detecting the torsional deflection of the AFM cantilever as it scans across the sample surface. Variations in friction are mapped in real-time, revealing heterogeneity in material properties. Specifications - Resolution: Sub-nanometer in vertical resolution. - Friction Sensitivity: PicoNewton-level detection of lateral forces. - Operating Environments: Air, liquid, and controlled conditions. - Applications: Tribology, polymers, nanocomposites, and biological materials.
